MFI testers in Mexico help you confirm melt flow index results fast, so you can release resin, verify incoming lots, and troubleshoot processing issues with confidence. A Melt Flow Tester, also called a Melt Flow Indexer (MFI), measures MFR (melt mass-flow rate) and MVR (melt volume-flow rate) for common thermoplastics used across Mexico’s plastics, packaging, automotive, and pipe industries.
Qualitest offers three Melt Flow Index Tester to match your workflow, from entry-level QC to fully automated, high-throughput testing.
What an MFI TesterM measures
An MFI instrument extrudes molten polymer through a standardized die at a controlled temperature and load. The system then reports:
- MFR (g/10 min) for production release and supplier verification
- MVR (cm³/10 min) for deeper process control and material comparison
- Melt density support (used when converting MVR to MFR, depending on method and setup)
Typical materials include PE, PP, ABS, POM, PS, PC, and fluoroplastics, plus many compounded or filled resins.
Where MFI testing is Used
- Plastics compounding and resin distribution: lot acceptance and COA verification
- Flexible packaging and injection molding: consistency checks that support stable processing
- Plastics pipe and fittings (PVC/PE/PP): production control across shifts and sites
- R&D and troubleshooting: comparing formulations, additives, and thermal history effects
- Supplier audits: aligning melt flow data across plants and partners
Standards supported
Qualitest MFI systems align with the most widely referenced melt flow standards used by laboratories and manufacturers:
- ASTM D1238 – Melt flow rate of thermoplastics
- ISO 1133 – Determination of MFR and MVR
These methods help you compare results across production sites and supply chains.
Why Choose Qualitest for MFI testing
- Practical model range: entry-level to fully automated platforms
- Standard-aligned outputs: supports ISO/ASTM reporting formats used globally
- Workflow-friendly controls: clear operation for production and lab teams
- Scalable options: accessories and configurations to match your materials and method needs
